emotionmeter

Python code for producing emotionality scores from Gennaro and Ash (2021).

To set up, from inside the main folder:

• type pip install -r requirements.txt in command line to install dependency packages (or pip3 in some systems e.g. Ubuntu)
• type python -m spacy download en_core_web_sm in command line to install the necessary language corpus for package spacy (or python3 in some systems).
  • It is possible to use other spacy-supported corpus in the format {lang}_core_web_{size}, where size could be sm for small, md for medium, or lg for large. Make sure to download it (here) and specify it in corpus argument in the EmotionMeter initizalizer (see the example below).
  • You may check the list of supported languages with spacy

and

• put the .csv file that contains your dataset in folder data. You may try with our dataset.
• make sure the word lists affect_list.txt and cognition_list.txt are in folder word_lists. You may also use your own or ours that is already provided (or from the same link if they are missing).

To use,

• import the package EmotionMeter and create the instance of it, specifying
  • data_path for the path to your .csv data, e.g. "data/smallExtractedTweets.csv"
  • text_column for the text column's name in the .csv, e.g. "Tweet"
  • corpus is the spaCy model for the pre-trained embeddings with format {lang}_core_web_{size}, e.g. "en_core_web_sm"
• for example usage, e.g.:

# import the package
from emotionmeter import EmotionMeter 

# and create the instance of it
meter = EmotionMeter(data_path="data/smallExtractedTweets.csv", 
                     text_column="Tweet", 
                     corpus="en_core_web_sm") 

# get df with calculated reasoning and emotional scores
meter_with_score = meter.calculate_score_and_other_stats() 

# print sample most emotional tweets
print(meter.show_sample_emotional_tweets(from_most_emotional=True)) 

# print odds ratio per hashtag in Democrat's tweets
print(meter.show_hashtags_sorted_by_odd_for_party(party="Democrat")) 

Some notes:

• If you would like to import the package into your own script outside the package folder, change the directory in the import part from ... import EmotionMeter on the first line
